Specification of Letters Patent.

Patented J an. 12, 1915.

Application filed May 1, 1914. Serial No. 835,700.

To all whom it may concern:

Be it known that I, WVILLIAM HENRY DALPE, a subject of the King of Great Britain, and residing at the city of Montreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Orthopedic Stocks for the Treatment of Club-Feet in Children; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention has reference to orthopedic stocks for the treatment of club feet and the object is to dispense with the usual plaster apparatus or boots usually used for hypercorrection of club feet in children and to provide in place thereof an extremely simple device which any physician can easily manipulate.

The invention consists essentially of a pair of (preferably metallic) stocks each comprising two ,rigid parts, a vamp and a sole, adapted to be connected together, with the deformed foot therebetween, the two parts of the stock being secured together in any suitable manner, as for instance by adhesive plaster. Means are also provided for interlocking two stocks together in such a manner that they retain the corrected inter nal rotation and eversion.

The invention will be better understood with the aid of the accompanying drawings in which- Figure 1 shows a general perspective view of a pair of stocks interlocked. Fig. 2 shows a perspective view of the pair of stocks disengaged. Fig. 3 is a longitudinal section through one of the stocks and F g. 4: is an underside plan of a pair of interlocked stocks.

Reference being had to the drawings, it will be seen that each stock comprises a sole 1 and vamp 2, said sole having the half ankle portion 3 and said vamp having the other half of the ankle. The vamp and sole portions are divided longitudinally of the foot and the stocks are shaped to the corthe foot takes when cured, a felt lining 4 eing preferably placed all around the interior of said sole and vamp to prevent chafing of the foot. ljhe sole portion of each stock is provided with ntegral loops 5 and 6 preferably at the inner side of the foot and engaged by lugs 7 and 8 extending from the same side of the vamp portion, this in order to retain the two parts of the stock together, the actual locking being accomplished by adhesive plaster at the outer side which is preferably passed through a loop 9 carried by the vamp portion, the plaster being stuck to both vamp and sole. The vamp portion is a little shorter than the corresponding sole so that the physician may Watch the circulation of the blood in the foot and correct the contraction of the toes of the foot by packing or other suitable means. The inner side of each sole portion is provided with a straight wall 10 and at the foot of each of said walls lugs 11 and 12 extend inwardly so that when the two stocks are placed together the walls 10 abut and the lugs of one wall engage beneath the wall of the other stock and thus prevent disengagement of the two stocks by relative movement in a vertical direction or in a direction longitudinal of the foot. The stocks however can by this means be brought together or disengaged by relative movement lateral of the feet and they are held together by strong rubber bands embracing the two stocks, or by other suitable means. The angle of each wall 10 is such that the internal rotation and eversion of the deformed feet must be gradually corrected before the two stocks can be engaged and any tendency of the feet to turn back again will be prevented by the lugs 11 and 12 which firmly hold the two stocks together against any disengagement other than lateral disengagement as hereinbefore mentioned.

The device herein described will be found of great advantage in the treatment of club feet for it is extremely simple to manipulate, there is nothing to break, no bandages are necessary and no amount of kicking by the child can disconnect the stocks or otherwise move the feet from their set corrected position.

It is obvious that modifications in the construction of the device herein described may be made, if desired, so long as 1 do not depart from the invention as set forth in the following claims for novelty.

What I claim is:

1. Orthopedic stocks for the treatment of club feet in children each comprising a sole part and a vamp part of rigid material interiorly fashioned with correct foot shape, means for securing said parts together with the foot in between and means for interlocking two of said stocks in a manner to retain the corrected rotation of the feet.

2. Orthopedic stocks for the-treatment of club feet in children each comprising a metallic sole part and a metallic vamp part interiorly fashioned into correct foot shape, each of saidparts having a half ankle portion and said vamp being a little shorter than the sole at the front end, means for securing said parts together With the foot in between, and means for interlocking tWo of said stocks in a manner to retain the corrected rotation of the feet.

3. Orthopedic stocks for the treatment of club feet in children each comprising a sole part and a vamp part interiorly fashioned to correct foot shape, one of said parts having loops at one side engaged by lugs on the other part for the purpose of securing WILLIAM HENRY DALPE.
